(CNN) — Three students at Pittsburgh’s Brashear High School were shot off school grounds Wednesday shortly after the last bell rang at 2:46 p.m., said Ebony Pugh, a spokeswoman for Pittsburgh’s public schools.
The students were approached by at least one gunman who came out of the woods and opened fire, the spokeswoman said. The students were shot as they walked to their cars.
The victims ran back into the school and notified the authorities. Their ages are unknown.
Jennifer Davis, a spokeswoman for Allegheny General Hospital, said the hospital received one shooting victim listed in stable condition.
